[0003] Currently, most instruments are installed using traditional direct flange or threaded connections, where the instrument's interface is fastened to the mating flange on the external pipeline using a set of circumferentially distributed bolts. This connection method has the following problems in practical applications: when the instrument needs maintenance, calibration, or replacement, the entire flange assembly must be disassembled, which is cumbersome and time-consuming, and may also affect the sealing of the external pipeline connection; while multiple sets of bolts can be disassembled, they lack a preliminary positioning structure, making initial misalignment easy, especially in confined installation spaces, hindering disassembly and maintenance operations. To address the shortcomings of existing technology, this invention provides an industrial automatic control instrument that facilitates connection, thus solving the above problems.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment discloses an industrial automatic control instrument that is easy to interface with, according to the appendix. Figure 1 To be continued Figure 5 As shown, the instrument includes a base 1, a splitting seat 2, an instrument body 3, a docking unit 4, and a sealing structure 5. The base 1 is securely assembled with the external pipe 6 via a flange structure. The splitting seat 2 is fixedly connected to the bottom of the instrument body 3 by welding or bolt fastening. The end of the splitting seat 2 is integrally formed with a butt joint 21. The base 1 is integrally formed with a fixing seat 11 that matches the butt joint 21. The butt joint 21 can be precisely embedded into the fitting groove of the fixing seat 11 for initial positioning. The docking unit 4 is installed on the base 1 to lock and limit the butt joint 21 and the fixing seat 11 after they are fitted together, ensuring the stability of their connection. The sealing structure 5 is set at the docking position of the butt joint 21 and the fixing seat 11 to improve the sealing performance after they are docked.

[0030] According to the appendix Figure 5As shown, the docking unit 4 further includes an integrally molded seat 41, a guide rod seat 42, an adjusting block 43, a threaded rod 44, and a pressure block 45; the integrally molded seat 41 and the base 1 are manufactured using an integrated casting process to ensure the structural strength of the connection between them; the guide rod seat 42 is fixedly connected to the top end face of the integrally molded seat 41 by bolt fastening or welding, and the axial direction of the guide rod seat 42 is perpendicular to the fitting direction of the mating joint 21; the adjusting block 43 has a circular hole that matches the outer diameter of the guide rod seat 42, and the adjusting block 43 is sleeved on the guide rod seat 42 through the circular hole to achieve a sliding connection with the guide rod seat 42; the threaded rod 44... Both ends are rotatably connected to the end bracket of the guide rod seat 42 via bearings. The axis of the threaded rod 44 is parallel to the axis of the guide rod seat 42, and the threaded rod 44 passes through the adjusting block 43 and forms a threaded connection with the threaded hole inside the adjusting block 43. One end of the threaded rod 44 extends to the outside of the guide rod seat 42 and is fixedly connected to a handle 441, which facilitates the operator to rotate the threaded rod 44. The pressure block 45 is fixedly connected to the side of the adjusting block 43 near the connector 21 by welding. The end face of the pressure block 45 near the connector 21 is machined with an arc-shaped pressing surface that matches the outer contour of the connector 21, which can increase the contact area with the connector 21 and improve the pressing effect.

[0031] According to the appendix Figure 4 As shown, the sealing structure 5 further includes an outer rubber ring 51 and an inner rubber ring 52; the outer ring side of the connector 21 is machined with an annular outer sealing groove, and the outer rubber ring 51 is embedded in the outer sealing groove. When the connector 21 is embedded in the fixing seat 11, the outer rubber ring 51 is tightly fitted with the inner ring side of the fixing seat 11, forming the first sealing line; the inner ring mating end face of the fixing seat 11 is machined with an annular inner sealing groove, and the inner rubber ring 52 is embedded in the inner sealing groove. When the connector 21 and the fixing seat 11 are fully fitted, the inner rubber ring 52 is tightly fitted with the inner ring mating end face of the fixing seat 11, forming the second sealing line. The outer rubber ring 51 and the inner rubber ring 52 together constitute a double seal, which can effectively prevent external impurities from entering or internal media from leaking.

[0032] According to the appendix Figure 1 To be continued Figure 3 As shown, the splitting seat 2 is U-shaped, with the opening of the U-shaped structure facing one side of the base 1, allowing the splitting seat 2 to span between two sets of bases 1, thus improving the overall compactness of the structure. The bases 1 are set into two sets, which are symmetrically distributed on both sides of the outer tube 6. Each set of bases 1 is L-shaped. The horizontal section of the L-shaped base 1 is connected to the outer tube 6 through a flange, and the vertical section faces the instrument body 3 and is machined with a fixing seat 11. The fixing seats 11 of the two sets of bases 1 are respectively engaged with the connectors 21 at both ends of the splitting seat 2, realizing bidirectional positioning of the splitting seat 2 and further improving the stability after docking.

[0033] According to the appendix Figure 5 As shown, a reinforcing rib 451 is fixedly connected between the pressure block 45 and the adjusting block 43. The reinforcing rib 451 is made of steel plate and is distributed between the connection surfaces of the pressure block 45 and the adjusting block 43. The two ends of the reinforcing rib 451 are fixed to the pressure block 45 and the adjusting block 43 by welding. The reinforcing rib 451 can effectively improve the structural strength of the connection between the pressure block 45 and the adjusting block 43, prevent the pressure block 45 from deforming due to excessive force during the pressing process, and ensure the reliability of the locking limit.

[0034] According to the appendix Figure 1 To be continued Figure 5 As shown, it is particularly important to emphasize that the number of docking units 4 matches the number of bases 1. That is, each set of bases 1 is equipped with a set of docking units 4. The two sets of docking units 4 are symmetrically arranged. The operator can synchronously rotate the handles 441 of the two sets of docking units 4 to make the two sets of pressure blocks 45 synchronously press the joints 21 at both ends of the splitting seat 2, ensuring that the force between the joints 21 and the fixed seat 11 is uniform, and avoiding docking offset due to excessive force on one side, which would affect the detection accuracy of the instrument.

[0035] According to the appendix Figure 1 To be continued Figure 5 As shown, it is particularly important to emphasize that the surface of the guide rod seat 42 is treated with chrome plating, with a chrome plating layer thickness of 0.05-0.1mm. This effectively improves the surface smoothness and wear resistance of the guide rod seat 42, reduces the sliding friction resistance between the adjusting block 43 and the guide rod seat 42, makes the sliding of the adjusting block 43 smoother, and avoids the increase in sliding clearance due to wear after long-term use, which would affect the accuracy of clamping and positioning.

[0036] Example 1: This example uses an industrial pipeline pressure testing scenario as an example, combined with the attached... Figure 1 To be continued Figure 5 Detailed workflow description: The workflow is as follows:

[0037] 1. Preliminary installation preparation: First, select appropriate flange connectors according to the pipe diameter of the external pipe 6. Fix the horizontal sections of the two sets of L-shaped bases 1 to the preset flanges of the external pipe 6 with flange bolts to ensure that the two sets of bases 1 are symmetrically distributed and firmly fixed. During the installation process, a level should be used to calibrate the installation level of the bases 1 to avoid the subsequent docking accuracy being affected by the tilt of the bases 1.

[0038] 2. Sealing structure 5 assembly: The outer rubber ring 51 and the inner rubber ring 52 are respectively embedded in the outer sealing groove and inner sealing groove of the butt joint 21 and the fixing seat 11. Before embedding, a small amount of silicone grease should be applied to the surface of the rubber ring to facilitate the installation of the rubber ring and improve the sealing performance, ensuring that the rubber ring is completely embedded in the groove without twisting or deformation.

[0039] 3. Instrument body docking: Hold the instrument body 3 and align the connectors 21 at both ends of the bottom split seat 2 with the fixed seats 11 on the two sets of bases 1. Slowly insert the connectors 21 into the fitting grooves of the fixed seats 11 until the end face of the connectors 21 is in contact with the limiting surface of the fixed seats 11. At this time, the U-shaped structure of the split seat 2 is just straddling between the two sets of bases 1.

[0040] 4. Docking and locking: The operator rotates the handles 441 of the two sets of docking units 4 respectively. The handles 441 drive the threaded rod 44 to rotate around the end bearing of the guide rod seat 42. Since the threaded rod 44 is threadedly connected to the adjusting block 43, and the adjusting block 43 slides with the guide rod seat 42 through the round hole, the rotation of the threaded rod 44 is converted into the linear sliding of the adjusting block 43 along the guide rod seat 42. The adjusting block 43 drives the pressure block 45 to move towards the docking joint 21 until the arc-shaped pressing surface of the pressure block 45 is tightly fitted with the docking joint 21. Continue to rotate the handles 441 until obvious resistance is felt, then stop rotating to complete the docking and locking.

[0041] 5. Testing and Use: Start the instrument body 3 and test the pressure in the external pipe 6. During the test, observe whether the data displayed by the instrument is stable, and at the same time check whether there are any signs of medium leakage at the docking position. If everything is normal, it can be put into normal use.

[0042] Example 2: This example uses an industrial fluid flow detection scenario where the instrument requires regular maintenance. It is combined with the attached... Figure 1 To be continued Figure 5 Detailed workflow description: The workflow is as follows:

[0043] 1. Initial installation process: The initial installation process is the same as steps 1-5 in Example 1. After completing the docking and installation of the instrument body 3, record the initial test data of the instrument as a subsequent comparison benchmark.

[0044] 2. Periodic maintenance disassembly: When the instrument body 3 needs to be periodically calibrated and maintained, first close the relevant valves of the external pipe 6 to release the pressure inside the pipe. Then, the operator rotates the handles 441 of the two sets of docking units 4 in the opposite direction. The threaded rod 44 rotates in the opposite direction, driving the adjusting block 43 and the pressure block 45 to move away from the docking joint 21 until the pressure block 45 is completely disengaged from the docking joint 21. At this time, the locking state of the docking joint 21 is released.

[0045] 3. Remove the instrument body: Hold the handle 441 of the instrument body 3 and slowly pull the instrument body 3 upward to disengage the connector 21 of the split seat 2 from the fixed seat 11 of the base 1. After removing the instrument body 3, check the sealing structure 5 on the connector 21. If the rubber ring is aged or damaged, replace it in time.

[0046] 4. Reassembly after maintenance: After completing the calibration and maintenance of the instrument body 3, reassemble the sealing structure, connect and lock the instrument body 3 according to steps 2-4 in Example 1. After reassembly, start the instrument, compare the test data with the initial reference data, and ensure that the instrument test accuracy meets the requirements before resuming normal use.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
